. The invention relates to heels for boots or shoes being more particularly intended for embodiment in heels having leather, rubber or like tread elements. i

The main object of the invention consists in the provision of novel mea-ns for detach-l ably securing the tread elements in place to permit worn elements being readily removed and a new one inserted .securely and with faio elity Y The invention consists in the combinations and arrangements of parts hereinafter Vdescribed and claimed.

The invention will be best understood by i reference to the accompanying drawing forming a part of this specification, and in which F ig." 1 is a perspectiveview of a heel enibodyin g my invention7 the pad being removed. 2) Fig. 2 is a perspective view of the removable pad.

Fig. 3 is a cross-section on line III-III of Fig. 1 with the padrin its position,

Fig. 4 is a perspective View of a second ern bodiment of the heel according to my invention.

Fig. 5 shows the pad in a perspective view.

Fig. 6 is a section on line VI-VI of Fig.l 4 with the pad in its position of use.,

Fig. 7 shows another construction of the heel in a perspective view and partly in section. Y

Fig. 8 is a cross section thereof.

Figs. 9 to 12 illustrate another form of the 35 heel with pad.

Fig. 9 is a side view of the heel body partly in section;

Fig. 10 shows the pad in a plan view;

Fig. 11 is the locking plate in a plan view .3 and Fig. 12 is a section thereof.

In the construction shown in Figs. A,1 to 3' a plate 1 is rigidly fixed by nails 2 to the heel body 8. The two outer edges 4, 5 runy parallel il each other and are bevelled to Vforni guides for a plate 6, attached to the heel pad 7. The

plate 6 is rigidly fixed to the pad 7 by means of nails if the paid 7 consists of leather and is attached to the pad if the latter consists of 53 rubber, by vulcanization, the plate being in maeemn'ain switzenandimrcn11;"193OQ". i

this case providedwith extensions embedded i in said rubber pad.V Thepplate 6 is provided 'with two slots 8, 9 vthe edges .10, 11 are bevelled `and adapted to engage the edges 4, 5 nof plate 1. Theupart of plate'6v between vthe slots 8, forms aspringyv tongue 12havingffa tooth-13 at its :free end. V'The tooth 13 engagesa'. notch :laat the fore end'of ,they platefl andV abuts `against the face'of the lplate 1in saidnotch. The' tooth V13 is provided with an incision ,15 60 and the v plate 1 with asmal'l notch: 16. The pad 1L (Fig. 2) isY pushed over plateV 1, fthe plates 1 and 6 engagingA eachother until the tooth `13 passes'into the recess 14. VThe/pad -7 is thereby secured onlthe heel. 1To displace 65 the pad7 a pointed tool is pushed into the incision 15` and vthe notch 16V whereby the partsV l and 6 are driven apart andthe tooth 13 is Y freed from its locking position in thearecess 14. The pad 7 maybe pushed back take'foif 70 theheel body v y ,t

" The device shown in Fig. 4 to 6 comprises an'angular plate 20 of metal sunk into a re cess ofthe'heel body 2l," andV rigidly fixed thereto.; On the plate two. raised guide "75 pieces 22, 23 are fixed, the outercurvededges 24,;25`thereof being bevelled., `The metallic frame 26'of the pad is provided .with arecess 27, the curved edge 28 of which being bevelled too. Thejedges 24, 25, 28 engage each other, 80 the frame 26 being heldthereby onthe heel bodyj .Toretain the pad 26 `on thelieel body 21 two` spring members 29,80 are fixed lto the'. frame 26 each being providedwith a hook "33 at its 'free end. The members 29, 30' areflo 85' cated withinthe. recess27 and the space 31 Y between-the two guide pieces '24, 2,5.y .The

hooks 33 passover the recessed faces 320i y b the said -pieces 24, 25 .firmly securin'githe'` frame 26,of `the fpad.- .By ra. suitableftool Y passed into therecess'27 the twofree ends 33 mayv befpressed against. each other until `the hooks 33 pass -from'the edges 32 and the pad-v maybe removed by pushing the `same.bacl` wards.` The pad may be of leather,.rubber or metal and pieces .ofsaid materials might Y be fixed to the frame 2'6'in any suitable man ner. aF or instance piecesof leather orrubber i maybeplaced-in the recess 85 of frame 26.

Heavy nails, etc., used iny mountaineering 1790 might be riveted in the saidvframe 26 or otherwise firmly attached theretoV or may be made" to form part of the frame 26.

i 'Figs 7 and 8 showra modified construction.

A; steel plate 40 isY arranged ina casting 41 which is formed to pass over the guide pieces 24, 25, thebeveled edges yof frame 41 and pieces 24, 25v engaging" each other. The frame 4l is provided With nails formed on the casting or riveted thereto, etc.v vThe springy members33 form parts of the steel plate 40,

the latter being formed by stamping. A slot v 45 serves for introducing a tool to bring the hooks l33-out-roff engagement and to freethe pad: f

Thepart 52 is provided with teeth/l projectingl radially and being Yspaced at regular distances apart. lA locking plate 55 is passed Vin a cross slot of the heel body 53, thev said plate 55 embracing the v:reduced middle portion of Vthe pad 51 closely p and passing tightly 'under the teeth 54.- The locking plate retains the pad 5l in its proper position on the heel body and is held by a springy member 5bV Which engages `a recess inthe heel bod7 53.i Said member 56 secures the locking plate V55 against accidental displacement and prevents the loss of the pad f 5l; The latter may be coveredby leather, rubber -or any other material.

fvvhiie I haveiuustmiea and described theV Y.

preferred form of construction for Vcarrying my invention into eect, this is capable of variation and modification Without departing from the spirit ofthe invention. I, therefk Y fore,.do not Wish to be'limitedk to the precise details ofthe construction set 'forth,"but desire to avail myself to such variations'and modifications as comevvithin the scope of the appendd claim.
